    libgimpwidgets, app: silence warnings about State 0 for GimpRuler and GtkScrolledWindow doesn't match 
state 128 set via gtk_style_context_set_state ()
    
    When run with GIMP_DEBUG=Gtk we get a lot of debug warnings for GimpRuler and once in a while for 
GtkScrolledWindow that State 0
    doesn't match state 128 set via gtk_style_context_set_state (). This happens because we didn't enter the 
current state flags of
    the widget but 0 and apparently Gtk isn't happy about that.
    
    Let's fix this by using the actual state flags by calling gtk_widget_get_state_flags.
